求助：sun v880 做raid1镜像不能恢复，显示Needs maintenance

机器是sun v880 ，装的是solaris 10，做得raid1，更换硬盘后，其他分区都能同步，但有一个硬盘一直不同步，显示State: Needs maintenance ，用metareplace -e d20 c1t0d0s1，同步大概3%左右就不同了，不知道什么原因，请各位帮忙。

d22: Submirror of d20

应该是盘有问题，换盘：


Invoke: metareplace d20 c1t0d0s1 <new device>

换硬盘

换盘吧。

这块盘是刚换的，然后镜像同步时出现问题了

各位大侠，还有哪位有建议呀，真的是硬盘坏了吗？

你执行以下：
#iostat -En
#dmesg|grep c1t0d0  
#dmesg |grep Requested Block:

把信息贴出来

新的配件 不代表就肯定没问题。

iostat -En 信息如下：

刚换就hard error 20了

刚换就报错了。再换一个吧。。

不会是硬盘坏了吧，是不是要把没有同步的那个分区重新再一下镜像就可以了

硬盘是有问题

再换，再，，，要坚持！

刚刚把信息给供货商那里发了

其余的slice的同步是不是都成功了；
建议你16G的slice的数据拷贝一份出来。

是的，其余的都成功了，是不是这一个分区做的有问题，这个分区好像是swap分区

继续换

    额新买的硬盘上周五到，装到系统上正常，周一来挂了，正在联系经销商换。

另外问下楼主：是希捷的scsi盘吗 ..................
